Question

【題目】Green Roofs （屋頂）

Why would anyone want to plant a garden on a roof? People are finding out that it is good for the environment and good for them.

Cities can be as much as four to ten degrees warmer than the countryside. Green rooftops can help cool the air in cities. One green roof will not do much to change the temperature of a city. However, when more buildings begin to convert their rooftops to green spaces, it can make a real difference. Buildings that are cooler also use air conditioning less often. This reduces the amount of energy a building uses.

Cities are usually more polluted than other areas. The plants on the rooftops can even help clean the air. Gardens in the city can also provide a place for birds and bugs to live.

One unusual rooftop garden is on the rooftop of Children's Hospital in Missouri. The garden covers an area of 7,500 square feet. It is a place for the children and parents to relax and be close to nature without leaving the hospital. The garden has flowers, fountains（噴泉）, and even a goldfish pond.

Another interesting garden is on the rooftop of the Royal York Hotel in Canada. The hotel's cooks can pick herbs（草本植物）they use fresh from the roof. Some other hotels and restaurants have rooftop gardens to grow plants. They just need gardeners to care for them. Rooftop gardens can dry out quickly in the summer sun, and vegetables need frequent watering.

Not all buildings have green rooftops. For one thing, green rooftops can be more expensive than traditional rooftops. Also, a roof needs to be flat and strong enough to support the weight of the garden.

In the past, not many people knew about rooftop gardens and how good they could be for the environment. But it is changing. You may want to keep your eyes on the skies when you walk the streets in your town or city. You never know when you might catch a look of a secret garden many feet above the ground.

Answer 1

【答案】

【1】C

【2】A

【3】D

【解析】

文章主要介紹在屋頂上種植花園，對環(huán)境有益，而且對他們個人也有益。綠色屋頂能降低城市的溫度，減少建筑能源的使用，幫助凈化空氣，給小鳥和蟲子提供生存的場所。文章介紹了密蘇里兒童醫(yī)院的花園屋頂和加拿大皇家約克酒店的花園屋頂。并講述了建綠色屋頂難的原因。最后總結(jié)現(xiàn)在情況發(fā)生了變化，越來越多的人知道了屋頂花園的益處。

【1】詞義猜測題。根據(jù)“their rooftops to green spaces, it can make a real difference”可知此處發(fā)生了“變化”，是從屋頂“變成了”綠色空間。convert的含義是“改變，變化”。故答案為C。

【2】主旨大意題。根據(jù)“green rooftops can be more expensive…” 和“a roof needs to be flat and strong enough to support…”可知此段講了并非所有建筑都有綠色屋頂?shù)膬蓚�原因：一方面，綠色屋頂可能比傳統(tǒng)屋頂更昂貴；此外，屋頂需要平坦且足夠堅固以支撐花園的重量。 推斷第六段的主旨是在講為什么建綠色屋頂比較難。故選A。

【3】推理判斷題。根據(jù)最后一段“In the past, not many people knew about rooftop gardens and how good they could be for the environment. But it is changing”可知在過去沒有多少人知道屋頂花園以及它們對環(huán)境的好處；但它正在改變。推斷出“現(xiàn)在越來越多的人知道了屋頂花園的益處”。故選D。

閱讀理解中詞義猜測題主要是考查學(xué)生從細節(jié)中理解文章的能力以及理解生詞的能力。做題時主要有以下幾種方法：①分析上下文所提供的情景和線索進行詞義猜測；②文章中在對該詞進行解釋說明時的一些解釋性的詞句；③利用同義詞反義詞或同義關(guān)系反義關(guān)系進行詞義猜測；④利用構(gòu)詞法進行詞義猜測。第一題是理解convert這個單詞的含義在選項中找到近義詞，可以分析上下文所提供的情景和線索進行詞義猜測，根據(jù)文中的“convert … to…”以及“difference”可知兩者發(fā)生了變化，有不同，所以推斷詞義為變化change。
